Ever wonder how much it costs them to build one? Who manufactures them? Does the Church have a manufacturing arm?
The parts are all standard, but high-end. Considering the copious amounts of hot glue, through-hole components, and the look of those copper tubes, I'm guessing they order boards from the usual suppliers then do final manufacturing in-house.
The boards look wave-soldered with some hand work, the pots are definitely hand soldered, there is heat shrink tubing on a bunch of connectors (but all the pieces are cut to slightly different lengths obviously by hand) on a bunch of connectors...
It looks to be on par with decent boutique analog audio gear from the 80s/90s, or careful hobbyist work. They really should be using Silastic instead of hot glue, though.
